Question

A street that is 156m long is covered in snow. City workers are using a snowplow to clear the street. A tire on the snowplow has to turn 39 times in traveling the length of the street. What is the diameter of the tire?

Use the value 3.14 for Pi . Round your answer to the nearest tenth. Do not round any intermediate steps.

Answer 1

156/39

Answer 2

wrong

Answer 3

That will give you it's circumfrence.

Answer 4

correct

Answer 5

around 13?

Answer 6

I lied...

Answer 7

i got 4

Answer 8

Then,
use the formula,

Cirmufrence = pi * d

Where d is the diameter.

Answer 9

4/3.142 = d

Answer 10

nvm I didn't... 12.4

Answer 11

^ close enough to 13

Answer 12

12.4 is the answer??

Answer 13

damn...12m tires, that's one monster plow :)

Answer 14

no

Answer 15

ok now im confused

Answer 16

you have the circumference of the tire as 156/39=4
C=pi*d
d=C/pi
where d is diameter, C is circumerference, as khan said

Answer 17

It's 4. like i said.
4m is the circumfrence.

Answer 18

oooh a cookie.....lol jk jk

Answer 19

Lmao. That's a Tyre. of 4m.

Answer 20

ameryn, you are lovely, sehr schoon!

Answer 21

oh ahhah thanks

Answer 22

156 = 39 * ( pi * D)
->D = 156/ 39 pi = 1.27m
